Specification of Letters Patent.

Application filed September 27, 1909.

Patented June 28, 1910.

Serial No. 519,825.

To all whom it may concern:

Be it known that I, LOUIS E. HELLER, a citizen of the United States, anda resident of New York, county and State of New York, have inventedcertain new and useful Improvements in Binders, of which the followingis a full, clear, and exact description.

This invention relates more particularly to binders in which a number ofloose leaves may be temporarily or permanently bound in book form.

The primary object of the invention is to provide simple and efficientmeans whereby a number of loose leaves may be slipped over and may bemade to engage a part of one member or element of a binder, and the saidleaves rigidly and detachably held by a second member having means as apart thereof to lock and hold the same to the other member.

Another object of the invention is to provide simple and efficientlocking means forming a part of a book in which loose leaves may be heldin book form.

A further object of the invention is to provide a simple and eliicientlocking member having relatively movable locking means adapted to engageanother member of the binder, and which locking means requires themanual operation of an independent device before the locking element ormember can be held to or removed from the other member.

With these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawings,which form a part of this specification, and will then be pointed out inthe claims at the end of the description.

In the drawings, Figure 1 is a section of one form of device embodyingmy invention, showing the same held within the cover of a book. Fig. 2is a detail plan view of the locking element or member of the binder.Fig. 3 is a detail plan view of the holding or supporting member of thebinder. Fig. 4 is a sectional plan view, partly broken away, of thelocking member. Fig. 5 is a longitudinal section, partly in elevationand partly broken away, of the binding means removed from the cover.Fig. 6 is an end elevation of the locking member or element Fig. 7 is asectional view of a diiferent form of locking means. Fig. 8 is a detailplan view of the locking member shown in Fig. 7. Fig. 9 is a detail planof the holding member. Fig. 10 is an enlarged sectional plan view,partly broken away, of the locking member. Fig. 11 is a longitudinalsection through the locking member. Fig. 12 is an enlarged fragmentarysection, showing how the locking member may be removably held to theholding member. Fig. 13 shows a slightly different form of locking meansfrom that shown in Fig. 12; and Fig. 14 is a detail view of one elementof the locking means of the detachable member.

The binder comprises a holding member 10 adapted to receive the loosesheets to be bound, and a looking or detachable member 11 both of whichmay be variously constructed. As shown the member 10 has a bar-like part12 from which project the posts 13, and said bar 12 may be fastened tothe back 14 of a cover 15, the latter being provided with a part 16which may be thrown back as is usual with books of various kinds.

The locking member or element 11 has a bar-like tubular body portion 17and is provided with apertures 18 spaced apart to correspond with theposition of the posts 13 so that said body portion 17 may be slippedover said posts above the base or body 12 of the holding member 10 andabove the leaves or sheets to be bound. A. relatively movable element orlocking device 19 is slidingly held in the body portion 17, and thisdevice 19 is provided with openings or apertures 20 which are adapted tofit over the posts 13 and to be brought into alinement with the openings18 of the body portion 17, and said element 19 is adapted when movedlengthwise within the body 17 to cause the side edges of the openings toengage the posts 13 in such a way as to hold the body 17 rigidly to theposts 13.

To move the member or device 19 within the body portion, I provide apost or block 21 having a part 22 to fit into one end of the tubularbody 17 and fastened thereto by means of rivets 23 or otherwise, and insaid block is a threaded opening which is engaged by a screw or element24. This screw 24 has its inner end adapted to engage one end of therelatively movable slide or device 19 and its other end is made squareor otherwise, as at 25, for the reception of the end of the key 26 bywhich the said screw 24 may be rotated in either direction. The block 21is recessed at 27 to permit the shank of the key 26 to engage the screw24,

and said key is guided in an opening 28 in a plate 29, the latter beingsecured to the block 21 by screws 30. When the key 26 is rotated toforce the screw 24 inward it will impart a similar movement to thedevice or locking element 19 to cause the edges of the opening. 20 toengage the posts 13 with sutficient force to hold the locking memberrigidly and removably to said posts. The device 19 is normally forced inthe opposite direction by a spring 31, one end of'which engages the endof the device 19 opposite that of the screw 24 and the other end is heldagainst a rigid block 32, which is held by rivets 33 or otherwiseadjacent to one end of the tubular member 17, the said spring serving tonormally force the slide or device 19 to a released position by causingthe openings '20 to be brought into alinement with the posts 13 so thatthe latter will not be locked to the member 19, in which case thelocking member 11 may be readily removed from the holding member 10.

The loose leaves with the usual holes for filing purposes are placedover the posts 13 after the member 11 has been removed and the saidleaves are then bound to the base portion 12 of member 10 by placing themember 11 over the posts 13 and by means of the key 26 rotating thescrew 14 so as to force the locking member or slide 19 into engagementwith the posts, the removal of the member 11 for the removal or placingover the posts of other leaves being accomplished as already described.

The binder may be used for binding different sizes of sheets or leavesand for this purpose, I provide a locking member 11 which may beprovided with openings 34 to receive similarly positioned posts of theholding member, and there may be addi-- tional openings 35 for stilldifferently positioned posts on the holding member. The locking element19 is also provided with openings therethrough corresponding to theposition of the openings 34 and 35 when the binder is to be used fordifferent sizes and kinds of leaves, the locking of the member to theposts being secured in the same manner as already described.

In Figs. 7 to 12 the holding member is substantially the same as alreadydescribed and the locking member 36 has it body portion 37 bar-like andtubular and movable in said member is a slide or locking device 38. Thisdevice 38 comprises two parts 39 and 40, each of which has a hole oropening 41 adapted to pass over the posts 13 of the holding member, andnormally forcing the parts 39 and 40 toward each other are the springs42, which are interposed between the outer ends of the parts 39 and 40and rigid blocks 43 located within the tubular body 37. The inner endsof the members 39 and 40 are provided wilth abeveled or cam surface 44which is adapted to be'engaged by the beveled or tapered end 45 of thekey to the body 37 substantially centrally there 7 of and secured to oneface of the body portion 37 is a plate 49 for strengthening purposes,andsaid plate may also be made'to serve as a guide for the key. By thismeans a two-part locking devicemay be provided in the locking memberinstead of acne part element as shown in Figs. 1 to 6. r

Fig. 13 shows a construction substantially similar to that shown "inFigs. 7 to-12 ex-f cept that the key or operating means is made in twoparts. As shown the handle portion 50 has its end 51 adapted to engage aslot 52 in the cam or beveled part 53, the latter engaging the threadedpost 48 as al ready described and serving when forced downward to spreadapart themembers 39 and 40 of'the locki-ng device 38. In thisconstruction, the cam part 53 may remain as a part of the locking memberwithout hav ing the entire part projecting beyond the plate 49. In thisconstruction there may be a plurality of: openings 54 and 55 arranged inpairs and corresponding in position to posts on the holding member sothat the said devices may be adapted for diiierent sizes and forms ofloose leaves.

From the foregoing it will be seen that a simple and efficient temporarybinder is provided for loose leaves; that simplemeansis provided wherebya member may be posi tively locked in such a way as to hold the leavesproperly to the holding member; that said device is adapted for use inconnection with different sizes and forms of leaves, and that saidbinder may be readily made and assembled.

Having thus described my invention, I claim as new and desire to secureby Letters Patent i 1. In a device of the class described, a casing, alocking member slidably arranged within said casing, a coiled sprmginterposed between one end of said locking mem ber and a bar locatednear the end of said casing, a member provided with a reduced portionextending within said casing, a screw adapted to pass through thecentral portion of said member and engage said sliding' member, themember which extends within the casing being provided with a recessedportion toaccommodatea member for rotating said screw, and a platepartially covering said recessed portion.

2. In a device of the class described, a casing, a locking memberslidably mounted in said casing, a bar extending transversely of saidcasing at a point near one end thereof, a spring interposed between saidbar and said locking member, a hollow member provided with a reducedportion adapted to extend within said casing, a screw adapted to pass,through the central portion of said bollow member and engage thelooking member, said hollow member being provided with a cut-awayportion, and a plate adapted to partially cover said cut-away portion.

3. In a device of the class described, a casing, a spring pressedlocking member slidably held within said casing, a hollow member havinga portion extending within said casing means carried by said hollowmember for actuating said locking member, and a key supporting devicesecured to said hollow member.

This specification signed and witnessed this 22d day of September A. D.1909.
